Application filed September 11, 1890. Serial No. 364,699. (No model.)

The obstructing the flow of the refrigerant therebeads or projections c3 and c5 are of a curved through and resulting in an uneven refrigeror semicircular form to support the inlet and 5c ating or cooling edect and otherwise interoutlet troughs D andD of the cooler. Below roo the inlet-trough D and above the outlettrough D' on the inner sides ot' the plates or standards C C' are projecting ribs, lugs, or flanges fand f ,respectively, each correspondingin outline to the outline of the ends a a' of the plates A A', so that said projections ff' enter the respective sides of the ends a a' to maintain the shape of the same and also to serve for locating the plates A A' in position on their side standards C C' preparatory to soldering the same together.

The inlet-trough D has one or more slits or lines of perforations, as desired, for distributing milk to the rounded end or top a of the plates A A' and to direct the flow to the outside of the corrugated plates A A'.

'Ihe plates or standards C C have at their upper ends outside lugs f by means of which the cooler may be pivotally suspended from any suitable support-such as brackets-so as to assume a perpendicular position and thus admit of the more even distribution and ow of milk on the outside of the corrugations of the plates A A' At one side of the lower end a' and passing through one side of the standards C C' is the inlet-pipe h for the water or other cooling-liquid for circulation through the serpentine passage a3 between the plates A A', and oppos'itely located in the other standard at the top end ais the outlet-pipe 7L' for such circulation. To pipe 7L is secured theiiexible or other pipe h2, leading to a tank or other supply, as usual or as desired, said supply or tank not being shown in the drawings. To bring the coupling connection between the pipes h and h2 near to the pivoted supports g or points of suspension of the cooler, so as to prevent the weight of the pipe 7b2 from swinging the cooler out of its perpendicular line, the end h4 of the pipe t is continued upwardly to near the top of the cooler, as shown in Fig. l.

The bottom trough D' is provided at any suitable point along its length with a nozzle d, having an outside flange d' at the lower end for the support of a rotatable spout cl2, which at its upper edges has inwardly-projecting flanges cl3 for engagement with the nozzleliange d'. The inner edges of the flanges cl3 are set at such a distance from each other as to pass on either side of the nozzle d and rest upon the annular flange d'.

The throat or passage between the flanges mayspout can now be turned in any desired direction so as to deliver the cooled liquid into any desired receptacle, thereby making the cooler more valuable for farmers use in cooling milk directly from the cow for shipment.

In the use of an apparatus of this kind it is well known that the milk orliquid to be cooled is introduced into thetrough D and is delivered therefrom upon the curved upper end of the cooling-plates, from whence it flows down said plates and into the trough D and from thence to a desired receptacle. In the meantime a refrigerant-such as water-is introduced by the pipe 7L and flows up the serpentine passage and is discharged at the pipe h', the supply being maintained by any suitable means.

The spacing wires or strips B, arranged between the corrugated plates A A', serve to strengthen and support the corrugations of said plates. l

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s-

I. In a milk-cooler, the standards having on their inner surfaces curved ribs for supporting and determining the contourof the rounded ends of the cooling surfaces or plates, in combination with the corrugated plates A A', having rounded ends, substantially as described.

2. In a milk-cooler, the standards having on their inner surfaces curved ribs terminating in a bend for supporting and determining the form of the end corrugations of the cooling-plates, in combination with the corrugated plates A A', iitted to said ribs, substantially as described.

3. In a milk-cooler having side standards, the corrugated cooling-plates arranged thereon, a bent metallic spacer arranged between the inner surfaces of the opposite standards and between said corrugated plates and supporting the corrugations of said plates, all combined substantially as described.

4. The combination, in a milk-cooler, of meansA for pivotally suspendingit, with a supply-pipe connecting with the lower end of the cooler and extending upward to or nearly to its point of support, substantially as described.

5. In a milk-cooler, the combination, with a discharge-nozzle having an annular fia-nge, of a rotatable and removable spout having inwardly-projecting flanges d3, extending along its upper edges to embrace said nozzle, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
